Above situations are rare but there are 3 situations though which, at one point or another, most frequent travellers through T2 will encounter which will keep them more than 10 mins going through fast track.
1. Busy times of the day at LHR - usually morning and evening block of flights the lines can build up quickly if there are reduced screening stations opened (eg staff break times or staff absences)
2. When there are strikes
3. When you are selected for a hand search
